MACHINE FOR SPINNING FIBROUS MATERIAL.

SPECIFICATION forming part of Letters Patent No. 344,170, dated June22,1886.

Serial No. 60,140. (No model.)

To all whom it may concern.-

Be it known that I, \VILLIAM A. DELMAGE, of Lowell, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Machines for Spinning Fibrous Material, of which thefollowing is a specification.

My improvement relates to machines for spinning fibrous material; andits object is to prevent waste of oil from spinning machinery. Iaccomplish this object by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 shows a front elevation of a portion of aspinning-frame provided with my improvement. Fig. 2 is an end elevation,partly in section, with the supporting-frame removed.

The operating parts of the machinery employed are similar to thoseheretofore used in spinning machines. No extended description istherefore necessary.

I have discovered that the electricity generated by the friction of thebelts and bands upon the pulleys which they run over can be utilized topreventt-he oil from leaving the points necessary to be lubricated.

I accomplish the object of retaining the oil upon the part requiring1ubri ationas, for instance,thespindle-step-bythedevice shown in Fig. 2.in which A is the spindle; B, the step; 0, the \vhir, D the cylinder,-E, the band driving the spindle, and F an accumulator, consisting of ametallic strip or wire provided with one or more points placed close tothe frictional surface of the cylinder and band, and terminating in apoint brought close to the top of the step, and also close to thespindle at such place, and said step is also provided with the groundconnection shown. The strip or wire, being insulated at all points frommetal contact, when the machine is started will accumulate and receivethe electricity from the belt or band and convey it through the step, toprevent the oil from being carried or rising up on the spindle andoverflowing the step, as it is demonstrated by observation is the case.I attribute this to the fact that, owing to the change in the electricalconditions of the step and spindle near it, the floating fibers ofcotton in the air cease to adhere to them as previously, and to carry ordraw up the oil by capillary attraction out of the step-reservoir. Thestep may alsobe provided with a ground connection, G, independ ent ofthe ground -connection given other parts of the frame, if so desired.This connection is found to be of utility where a wooden step-rail isusedas, for instance, in mules.

As in other prior machines, I deem it. also advisable to employaccumulators H and K in proper electrical relations with the cylinder Dand driving-belt, each having proper and direct groundconnections, J k.The ground-connections are easily made through the gas or water pipes.The accumulators are provided with many teeth or points to readilyattract and take up the electricity.

My invention, while applicable to diflerent machines, is especiallyadapted for mule-spinning or other frames on which a fine, smooth, andeven thread is to be produced.

\Vliat I claim as new and of my invention 1. The combination, with thedriving-belt or band E, the wire F, and the lubricated hearing B, of theshaft or spindle A and an electrical ground-connection leading trom saidbearing, substantially as described.

2. The combination, in a machine for spinning fibrous material, of aspindle, spindlebearing, and belt-driving pulley or cylinder with anaccumulator adapted to receive the electricity generated by one portionof the machinery and convey it to the spindle at a point near thebearing, substantially as described.
